COVER FOR AUTOMOBILE TIRE-VALVE STEMS.

Applicationflled September 24, 1926. Serial No. 137,515.

This invention relatesgenerally to looks, and has more particularreference to a cover for automobiie tireevalve stems that may be,

readily applied toftired vehicle wheels for 6 enclosing the valve stemsof the tires in order that the usual retaining nuts cannot be removed byunwarranted persons for obviously preventing out greatly damagin thesame;

One of the main jects of the invention is to provide a device of thischaracter that is extremely simple of construction, one that may bereadily installed for permanent association with the wheel.

A further and important object of the invention is to provide a devicethat is also so constructed as to prevent malicious persons fromtampering with the valve stem and ex hausting the air from the tire.

Other objects and advantages of the invention will become apparent fromthe following description taken in connection with the accompanyingdrawing.

In the accompanying Nowv having particular reference to, the

drawing, A designates a conventional vehicle wheel upon the rimpneumatic tire G. The invention B of which is the usual se consists of:an open er 40 endedmetallic tube 5 preferably of circular formation, thel wer end of which is formed with a cross plate 6, the ends of which arebent downwardly as at 7--7 to fit along the opposite side of the wheelfelly, the lower ends of said downwardly bent portions 7--7 beingproperly curved as at 88 for ti ht fit around the flangles of the rim B.

gedly secured to t e open upper ends of the tube 5 as at 9, is a lid 10,to the inner side of the outer wall of which is secured a dependingspring metal plate 11. This plate 11 1s formed adjacent its lower endthe theft of the tires with with a slot 12 for receiving a tapered lug13 upon the interior of the tube 5 when the lid 11 is closed, so as toobviously prevent the raising of said lid. Y

' The tube 5 is formed directly beneath its open upper end with asquare-shaped hole .14.- for receiving the squared stem of akey 15, thepurpose of which is to forcibly move .the spring metal plate 11 out ofengagement with the lug 13 so that the lid may be raised.

The extreme lower end of the spring metal plate is bent slightlyinwardly as at 16 for disposition within a depression at the interior ofthe tube 5 as in Fig. 2, there be ing pivoted to the tube as at.17directly beneath the lower curved end of the spring metal plate, aclover-shaped latch plate 18,

the various wings of which will enga e over the lower end of the springmetal p ate, so

as to prevent the. same from being forced out of engagement with the lug13, unless said latch plate has been turned to the proper position.

The tube 5 is formed directly beneath this latch plate 18 with aT-shaped slot 19,

through which is to be passed the headed end 20. of a suitable key 21.When the head of the key is inserted in the slot, the same will engagebetween adjacent wings of the latch plate 18 so as to facilitate theturnin of the same in order that it may be move out of engagement withthe lower end of the spring metal spring plate after which the space maybe forcibly swun rearwardly by reason of the key 15, for o'viouslypermitting of the of the lid 10 so that access may be raising the valvestem D to permit of the rehad to moval of the valve stem locking nut orto allow of the proper inflation or deflation of the t' novel, simpleand efficient form of Ire C. v

It will thus be seen that I have provided a highl the valve stems ofautomobile wheel tireswhich is always necessary to permit of the removalof the tire with respect to the wheel.

Even though I have herein shown and described the inventionas consistingof certain details of construction, it is nevertheless to be understoodthat some changes may be made therein without affecting the spirit'andscope of the appended'claim.

Having thus described my invention, what I claim as new is As a newproduct of manufacture, a cover for an automobile tire valve stem comrising 5 an open ended tubular cylinder, a li hing edl connected'to oneend for closing said end retaining means for said lid, and meansconnected to the opposite open end of the cylinder whereby it ma bedetachably connected with an automo ile wheel rim, said 10 meansembodying a plate having right anilar extensions terminating inresilient hoo constructed to conformto and detachably engage the wheelrim flanges.

In testimony whereof I afiix my si nature.
